## §SELF — miscsubjects capability (paste without context)
**Principle:** Self-explaining payload — no external context required. This _self block is the capability: what it is, how to run it, how to change it, and where to look next.
**Path:** OIP > OIP > OIP_REPLAY
**Capability:** `OIP_REPLAY` — Re-fire a past invocation with its recorded input. New receipt links replay_of to the old one.
**When to use:** Cyrus says "replay that", "run inv_x again", "re-fire it as it was".
**RUN NOW (open this URL):** https://miscsubjects.com/api/dispatch?invoke=OIP_REPLAY&body=inv_wvitbmiym6&share=<TOKEN>
**Example call:** [OIP_REPLAY]inv_wvitbmiym6[/OIP_REPLAY]
- **type · runner:** tool · fn · oip
- **run it:** Open run_now (URL, fires the example), or POST https://miscsubjects.com/api/dispatch {"key":"OIP_REPLAY","body":"inv_wvitbmiym6"}. From the router: [OIP_REPLAY]inv_wvitbmiym6[/OIP_REPLAY]
- **inputs:** {"args":"$1 = invocation id (inv_…)."}
- **outputs:** { ok, result, invocation, yield, _self } — result is this object's output; yield is tokens/cost/material; invocation is the ledgered record.
- **auth · risk:** none · low
### Machine Contract
- Read this article first; do not infer the row shape from memory.
- If acting with a URL-only tool, open run_now after replacing placeholder args.
- If the call returns ran:false or proof.ok:false, read the receipt and repair the failed invocation instead of narrating success.
- If the token denies the call, report the denial exactly; do not switch to a broader action unless the owner supplied a broader token.
### Invocation, Ledger, Repair
- root tree: https://miscsubjects.com/api/dispatch?map=1&format=markdown
- parent system article: https://miscsubjects.com/api/dispatch?map=OIP&format=markdown
- append-only ledger: https://miscsubjects.com/api/invocations?object_id=OIP_REPLAY
- receipt pattern: https://miscsubjects.com/api/dispatch?receipt=inv_ID&share=<TOKEN>
- replay: POST /api/dispatch {"replay":"inv_ID"}
- repair: POST /api/dispatch {"key":"OIP_REPLAY","body":"corrected args","repairs":"inv_ID"}
### Troubleshooting
- **unknown key** — Use the did_you_mean links or ask URL; never guess another key. · https://miscsubjects.com/api/dispatch?ask=OIP_REPLAY
- **argument/body mismatch** — Read inputs/example_args here, then retry with repairs: inv_ID so lineage closes. · https://miscsubjects.com/api/dispatch?key=OIP_REPLAY
- **expired or corrupted token** — Report token_expired/token_corrupted from the response; owner mints a fresh scoped link. · https://miscsubjects.com/api/dispatch?explain=1&share=<TOKEN>
- **tool returned ok:false / exit nonzero** — Do not call it sent. Read the receipt, correct the body, fire a repair. · https://miscsubjects.com/api/dispatch?receipt=inv_ID&share=<TOKEN>
### Logical proof (verify each step)
1. Every capability is an invokable object with its own _self — this block. → https://miscsubjects.com/api/dispatch?key=OIP_REPLAY
2. You run it by POSTing to /api/dispatch; in a model turn the router tag is [OIP_REPLAY]args[/OIP_REPLAY]. → https://miscsubjects.com/api/dispatch?registry=1
3. Every invocation is ledgered with actor, cost, and material/waste. → https://miscsubjects.com/api/invocations?object_id=OIP_REPLAY
4. You can ask the build for capabilities in plain language. → https://miscsubjects.com/api/dispatch?ask=Re-fire%20a%20past%20invocation%20with%20its%20recor
5. The whole build is one self-describing map, with the terminal key. → https://miscsubjects.com/api/dispatch?build=1
